One subpoena orders Dopp, who was suspended on July 23 for 30 days as a result of the scandal, to answer questions under oath at an Oct. 29 hearing of the Republican-controlled committee.

A lawyer for Dopp, Terrence Kindlon, said his client would “cooperate fully.”

The subpoena also orders Dopp to turn over “all documents,” including personal e-mails and other electronic messages, relating to the scandal.

It seeks “any and all documents, manuals and protocols with regard to the executive chamber [the governor’s] Blackberry system, including the server used for the handling and storage of the administration’s Blackberry communications.”

Kindlon said his client would comply with that request as well.

The second subpoena orders Baum to provide the committee with all written and electronic documents relating to the scandal as well as the same technical data sought from Dopp.

Spitzer last night accused the Senate of an “abuse of power,” and said he would hire outside lawyers to fight the subpoena for gubernatorial documents.

Dopp and Baum refused to answer questions under oath to investigators for Attorney General Andrew Cuomo, who launched his investigation of the scandal on July 5 after The Post wrote about the plot against Bruno directed by Spitzer’s aides.

A committee spokesman said subpoenas for testimony from Baum, acting State Police Superintendent Preston Felton and William Howard, Spitzer’s since-demoted homeland security adviser, would soon be served as well.

The Cuomo report found that Dopp, Howard and Felton conspired to have the State Police gather evidence purporting to show Bruno misused a state helicopter for political purposes.

Dopp then leaked the information to The Albany Times-Union.

Cuomo said no misuse of the aircraft by Bruno had occurred.

“We have a constitutional obligation to carry out our legislative responsibilities in response to findings of misconduct within the Spitzer administration,” said Investigations Committee Chairman George Winner (R-Elmira.) “To do that effectively, we need a clearer picture of what occurred, when, who was involved, and how it was carried out.”

The state Public Integrity Commission also is probing the scandal. Cuomo’s report recommended disciplinary action against Dopp, Howard and Felton, but found that no criminal conduct had occurred.

A report last month by Albany District Attorney David Soares, a Spitzer political ally, found no wrongdoing of any kind. But critics noted that Soares failed to put any of those questioned – including the governor – under oath.
